Documentation on using EF Core is available at https://docs.efproject.net.
This project is for Entity Framework Core. Entity Framework 6.x is still under active development at https://github.com/aspnet/EntityFramework6.
Entity Framework (EF) Core is a lightweight and extensible version of the popular Entity Framework data access technology.
EF Core is an object-relational mapper (O/RM) that enables .NET developers to work with a database using .NET objects. It eliminates the need for most of the data-access code that developers usually need to write.
The source for SQL Server, SQLite, and InMemory providers are included in this project. Additional providers are available. For a complete list, see https://docs.efproject.net/en/latest/providers/.
For more details on the release schedule, see the Roadmap article in the wiki.
